Small Type High Gain Indoor Yagi Antenna

Abstract

An indoor Yagi antenna includes an antenna body, a PCB substrate and an antenna bracket. The antenna body includes an upper shell and a lower shell which form an inner cavity containing the PCB substrate including an end connected to a signal director, an end connected to a signal reflector, a middle section connected to a main antenna oscillator, the portions of the three which are electrically contacted with the PCB substrate respectively, are wrapped by the upper shell and the lower shell, the bottom surface of the lower shell is provided with a feed line terminal block connected to the PCB substrate; the antenna bracket includes a bracket rod that can be flexibly bent, the top end of the bracket rod is provided with a universal adjusting mechanism connected to the lower shell, and the bottom end of the bracket rod is provided with a bracket base.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to Chinese patent application No. 201810655028.7 filed on Jun. 23, 2018, the contents of which are incorporated herein by reference in their entirety.TECHNICAL FIELD[0002]The present invention belongs to the field of communication technology, and specifically relates to a small type high gain indoor Yagi antenna suitable for indoor installation and use.TECHNICAL BACKGROUND[0003]Due to the large size of a traditional high-gain TV Yagi antenna, the installation thereof requires a specific antenna bracket and a specific embracing rod, meanwhile, due to the directional characteristic of the Yagi antenna, it is extremely inconvenient to adjust the orientation and the angle of the antenna after installation. In addition, due to the size and shape thereof, a user can only choose to mount the antenna in an outdoor location such as a top floor of a building, an outdoor environment and various weather factors cause t...

AI Technical Summary

Benefits of technology

The present invention is a new antenna design that has several advantages over previous designs. By using a high-efficiency PCB barron and high gain amplifier, the performance of the antenna can reach the standard even when mounted indoors. The antenna is protected by the upper and lower shells and is fixed using a detachable and adjustable bracket. The suction disk of the bracket discharges air by pressing downwards, creating a vacuum state that allows for easy mounting on a mounting plane. The antenna can be mounted at any angle and the orientation of the antenna can be adjusted by loosening or tightening the adjusting nut. This solves the use problem of the directional characteristic of the Yagi antenna. Overall, the new design provides improved performance and flexibility compared to previous antennas.

Problems solved by technology

Due to the large size of a traditional high-gain TV Yagi antenna, the installation thereof requires a specific antenna bracket and a specific embracing rod, meanwhile, due to the directional characteristic of the Yagi antenna, it is extremely inconvenient to adjust the orientation and the angle of the antenna after installation.

In addition, due to the size and shape thereof, a user can only choose to mount the antenna in an outdoor location such as a top floor of a building, an outdoor environment and various weather factors cause the use time and service life of the Yagi antenna to be greatly reduced.
